Lace blocker



FIG. 1 is a first view of a lace blocker, showing my new design;

FIG. 2 is a second view thereof; and,

FIG. 3 is a third view thereof.

The broken line showing of lace segments is for illustrative purposes only and forms no part of the claimed design.

Any surface of the design not shown, including any part of any such surface, is not part of the claimed design. 

I claim the ornamental design for a lace blocker, as shown and described.
